Sent in my TA-49 in January to be rebuilt.A couple of 20psi runs on the street left smoke pooring out of exhaust.Sent turbo back to Limit and sent back new turbo.Reinstalled turbo and this one lasted a week.?But maybe there's a problem causing this.I'd like someone to figure this out before I bolt on a new turbo.But I don't know where to go for this problem.Any ideas out there?Getting frustrated with this car.Need help.
